To all whom t may concern.'

Be it known that I, JOHN KoRHoNEN, a a citizen of Finland, (having taken out my first United States citizenship papers,) and a resident of Englewood, in the county of Bergen and State of New Jersey, have invented a new and Improved Snowplow, of which the following is a full, clear, and eX- act description.

This invention relates to snow plows and has for an object to provide an improved construction in which the snow may be discharged at a plurality of dierent points by a slight re-arrangement of the rear part.

Another object of the invention is to provide a snow plow in which substantially the full width of the plow structure acts to scoop up snow so that the plow structure may travel along over the surface which has been cleaned.

Another object of the invention is to provide a structure in which any desired layer of snow may be removed.

In the accompanying drawings:

Figure 1 is a top plan view of a snow plow disclosing an embodiment of the invention.

Fig. 2 is a longitudinal vertical section through Fig. 1 on line 2 2.

Fig. 3 is atop plan view of the rear part of the plow shown in Fig. 1 with an attach-` ment showing how the snow may be diverted to one side instead 'of both sides as shown in Fig.J 1.

Fig; 4 is a view similar to Fig. 1, but showing an arrangement of side boards whereby the snow will be discharged at the rear.

Fig. 5 is a fragmentary perspective view showing one of the side boards used in Fig. 4.

Referring to the accompanying drawings by numerals 1 and 2 indicate runners and 3 a stationary body bolted or otherwise rigidly secured to the runners, said body carrying a seat 4. a bracing structure 5 and a lever and rack 6. In addition the plow structure 7 is pivotally connected with the body 3 by bolts 8 and 9, said bolts also connecting an adjustable nose 10, which by its position determines the thickness of snow removed. The nose 10 has upstanding ears 11 on each end through which the bolts 8 and 9 pass` and t"o one of which the link 12 is secured, said link being pivotally connected at 13 to lever l6 whereby the nose may be raised and lowered as desired.

As above stated the plow 7 is pivotally connected to the body 8 whereby it may move upwardly and downwardly. In order to properly support the rear of the plow 7 stiifening beams 13 are bolted or otherwise rigidly secured to the bottom 14 of the plow 7, said beams carrying `a bolt 1 5 which are adapted to pass through any of the apertures 16 in the respective upstanding brackets 17. Preferably there are only two brackets 17 as illustrated in Figs. 1 and 2, but more may be provided if desired. When the plow is discharging from the rear end as shown in Fig. 4 the bolts 15 are adjusted so as to elevate the rear end of the bottom 14 as much as possible. This is in order that a Patented Jan. 13, 1920.

sled or wagon at the rear of the plow may receive the snow directly vfrom the plow without the addition of any eXtra mechanism. The plow may be pulled by horses or moved through the streets or roads by any desired power, as the nose 10 engages the snow said snow will be forced on to the bottom 14 and gradually out the rear end, or the sides as illustrated in Figs. 1` and 3. The illustrations in Figs. 1 and 2 show delecting boards 18, 19, 20 and 21 for defleeting the snow to the sides ofthe plow. These boards are provided with one or more ears 22 through which a suitable bolt 23 is designed to pass, said bolt also extending through a suitable aperture in bottom 14.

In suburban or country roads the arrangement shown in Fig. 1 is desirable as the center of the road is cleaned and the snow piled on each side. In some instances it may be desired to pile the snow on one side ot the road, when this is the case a deflecting board 24 is provided as shown in Fig. 3 which is held in place by a number of bolts or screws 23. The snow, whether deflected to one side, both sides, or discharged at the rear end as shown in Fig. 4, will be moved by the action of the snow against the bottom 14 whereupon no unnecessary mechanism is necessary to deposit the snow at the desired point.

It is to be understood that the snow is actually gathered up and discharged at the point desired instead of being pushed to one side bv sweepers and snow plows now in general use.

The side walls 25 and 26, Villustrated in F ig. 4, are merely straight lwalls having suitable ears for receiving clamping bolts 23, the forward part thereof, however, being capable of extending between the side walls 27 and 28 of the plow and the frame 3 so as to be properly clamped theretoV by suitable bolts. The various other deeeting Walls are` also arranged with an extension to ft betweenthe walls 27 and 2S and the frame 3.

What I claim is:

A snow plow comprising a tractor, a plow structure mounted on the tractor formed with a flat bottom extending from the front to the rear of the tractor, said body having a number of openings therein adjacent the rear, a plurality of deiecting members arranged at the rear formed with ears, and a bolt extending through each of the ears and certain of said openings for clamping the deleeting members in position, said bolts and said delectng members being shifta'ble so that the bolts will occupy different openings as desired according tof thevposition desired for the deflectors.
